Question

The diameter of two circle plates are respectively 10 cm and 24 cm what is the diameter of a plate which has area equal to the combined area of the two given kids

Answer 1

Answer:

26 cm

Step-by-step explanation:

Area of 1 st Plate = (22/7)(D/2)² = (22/7) (10/2)² = (22/7)* 25

Area of 2nd plate = (22/7)*(24/2)²= (22/7)*144

Total area = (22/7)*(25+144) = (22/7)* 169 = (22/7)* 13²

= (22/7)*(26/2)²

Dia of new plate = 26 cm
